- By virtue of the line contact between rolling elements and raceways, cylindrical roller bearings have high radial load capacity and are suited for high-speed applications
- With a patented high strength cage design in pressed steel our cylindrical roller bearings are comprised of machined brass or polyamide and offer low noise, low heat generation and, for more arduous applications, can be supplied in a range of advanced special materials
- NJ: Two outer flanges, one inner flange
